Alloy 400 (UNS N04400) is a solid-solution Nickel/Copper alloy that can be hardened only by cold working. It has reasonable strength and toughness over a wide temperature range and excellent resistance to many corrosive environments. Alloy 400 is widely used in many fields, especially marine and chemical processing. Typical applications are valves and pumps; pump and propeller shafts; marine fixtures and fasteners; electrical and electronic components; springs; chemical processing equipment; gasoline and fresh water tanks; crude petroleum stills, process vessels and piping; boiler feedwater heaters and other heat exchangers; and deaerating heaters.

Alloy 625 is a nickel-chromium-molybdenum alloy used for its high strength, excellent fabricability and outstanding corrosion resistance. Service temperatures can range from cryogenic to 980°C (1800°F). Alloy 625 strength is derived from the solid solution strengthening effect of molybdenum and niobium on its nickel-chromium matrix. Thus precipitation-hardening treatments are not required. This combination of elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization.

Alloy 276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high chromium, molybdenum and tungsten contents make the alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition. Alloy 276 is widely used in the most severe environments such as mixed acid chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and recovery of sour oil and gas. Please note that we have a minimum order value of £10,000.

Alloy 22, is a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media. This nickel alloy also has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions. Alloy 22 has resistance to oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, sea water, brine and many mixed or contaminated chemical solutions, both organic and inorganic. This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. This is beneficial in multi-purpose plants where such “upset” conditions occur frequently. Please note that we have a minimum order value of £10,000.

Nickel based alloys are very useful materials for the manufacture of high quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications. Nickel alloy tubes offer excellent corrosion resistance, high melting points and resistance to oxidationIn addition to their high melting points and resistance to oxidation and corrosion, nickel alloys are very ductile. Nickel based alloys have a higher ability to accept alloying elements in solid solution than other stainless steel or iron-based alloys. They cantherefore maintain higher metallurgical stability. The combination of high alloying with multiple elements can provide very good corrosion resistance in a wide range of environments while still maintaining good welding and forming characteristics.

Our weld wire sheathing material is used in both flux cored wire and metal cored welding wire processes. The wire sheathing is formed into a tubular product by our customers and the center of the tube contains the ‘fill’ (flux, metal powders, etc) to bring the wire to the desired chemistry. The finished wire is used across a wide breadth of industries in processes such as: Submerged Arc Welding (SMAW) Gas Metal Arc Welding (GMAW) Wire Arc Thermal Spray Flux cored welding wire producers use our metal sheathing materials to prepare finished wire for thermal spray and in surfacing applications, in high temperature and corrosive environments. Cobalt Our Ductile Cobalt Alloys are used to produce wire to hardface applications in the construction, mining, and oil and gas industry. Our proprietary process allows us to offer high Cobalt containing products (91% Cobalt or more) while maintaining a highly ductile strip for wire forming.

Alloy 800, 800H, and 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in alloy 800H/HT and the addition of up to 1.20 percent aluminium and titanium in alloy 800HT. Alloy 800 was the first of these alloys and it was slightly modified into Alloy 800H. This modification was to control carbon (.05-.10%) and grain size to optimize stress rupture properties. In heat treatment applications Alloy 800HT has further modifications to the combined titanium and aluminium levels (.85-1.20%) to ensure optimum high temperature properties. Alloy 800H/HT was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both carborisation and to embrittlement from precipitation of sigma phase. Please note that we have a minimum order value of £10,000.
